In a certain discrete math class, all the students can program in Python or C++ or Java. See the detail below: 63 can code in Python, 50 in C++ 32 in Java 34 in Python and C++ 15 in C++ and Java 25 in Python and Java 9 in Python, C++, and Java. i) How many students are in this discrete math class? ii) How many students can only code in Python, but not in C++ and in Java? For each math expression, type in the equivalent Java expression, written using the same or equivalent operators as the original math expression. Use Math-class fields and/or methods wherever possible. Use the same variable names as in the math expressions. (You might notice that most of them are standard formulas used in various math courses you have taken.) Assume that each Java variable is a double variable.
